BARRELNCONNECTION.

FECIFICATION forming part of Letters Patent No. 321,520, dated July 7,1885.

Application filed April 2l, 1884. (No model.)

To @ZZ infront t may concern:

Be it known that I, Triro'rnv OBRrnN, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in Barrel-Connections, of which the following description,in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

The object of this invention is to provide barrels for beer or otherliquors with a connection which shall secure the retention of thecontents of the barrel after the same has been iilled and until it is tobe used, and which will then permit the ready attachment thereunto of apipe or faucet wit-hout loss of liquor or gas.

In accordance with my invention, I have provided the head of the barrelwith a headed bushing, screwthreaded externally for insertion in thebarrel and internally for the reception of a flanged plug threadedexternally at one end to enter the bushing, and at the other end, at theopposite side of a llange thereon, with another thread to receive apipe-coupling or faucet, thc said flange being shaped to be engaged by awrench, the llange entering an enlarged chainborcd head in the outer endol the bushing, as will be described. Longitudinal movement of the pluginto the barrel effects the uncovering of ports in the plug which permitthe outward flow of the liquid, and a similarbnt reverse movement of theplug effects the covering ofthe parts for cutting off the outflow of theliquid. The invention consists in the detail of construction hereinafterset forth and claimed.

Figure l, in section, shows one end of a barrel with my improvedconnection applied and in position to retain the contents of the barrel.Fig. 2, in full lines, but on a larger scale, represents alongitudinalsection of the connection Fig. l. Fig. B shows the cap removed and aVcoupling of a pipe partially turned upon the plug preparatory toengaging the flange of the plug by the wrench to be described. Fig. 4shows the plug after it has been moved longitudinally backward in thebushing; Fig. 5, a front view of Fig. 4; and Figs. 6 and i are differentviews of the wrench.

The bushing A, threaded externally at 2 to enter the wood of thebarrel-head, has an enlarged chambered head, A2, (see Fig. 2,) forin-'ing a shoulder, 3, for contact with the barrelhead. The bushing` isthreaded internally to receive the sc1ewthreaded inner end of the hollowplug B, provided with ports b for the y passage of tluid and gas. rlheplug at its inner end beyond the screw-threads, which engage theinterior 4of the bushing, is reduced in diameter and provided with anextension, b, which is screw-threaded and receives upon it aleather orother packing washer, c', anda nut or collar, c, so that thelongitudinal movement ot' the plug outward in the bushing will cause theports b to be brought within the bushing and the packing against the endot' the bushing, thus preventing the escape of lluid, and in suchcondition, as shown in Figs. l and2in full line, the cap d will bescrewed upon the screw-threaded outer cud, b, of the plug at the rightof the ilangc D", the said cap closing the outer end of the plugclosely, a washer, e, being preferably used in the cap. The flange bl isprovided with a series of notches, if, for the reception ot' the prongsl. of a wrench, f. A filled barrel with the bushing stopped, as in Fig.l, having been removed from the brewery, and it being desired to use theliquid therein, the cap d will first be removed. If the liquid is beer,and is to be taken out through a long pipe and stationary faucets inanother story, the end of the plug will be placed next the end of apipe, Il., having a loose coupling, h', provided with ahandle and apacking, fr', and the coupling will be turned upon the outer end of theplug` until the parts are as in Fig. hwhen the wrench f will be appliedoutside the coupling, so that the prongs/l will enter the hollow head A2and the notches Ii of the ilange of the plug, after which the plug willbe rotated by the said wrench and will be moved longitudinelly into thebushing, removing the packing e from the inner end of the bushing,uncovering the ports b, such movement of the plug also causing thepackiu g m to be forced against the seat m and the coupling to becarried into the hollow head of the bushing, as in Fig. fl, crowding thepacking m against the seat m.

In case it is desired to insert a faucet into the barrel, the faucet,provided at its inner end with ascrew-thrcad to engage the threaded endIOO . biof the plug, maybe applied to the latter, the

cap d having been first removed. Fig. 2, by dotted line, shows part of afaucet in the position it will occupy. The enlarged head of the bushingis let into a recess in the barrel-head, which is nearly as thick as thebushing is long, and the bushing and plug are therefore confined withinthe chine.

I claiml. The bushing A,havi ng the enlarged chambered head A2, andscrew-threaded externally to enter the barrel, and also screw-threadedinternally, combined with. the longitudinallymovable screw-threaded plugB, tting the threaded interior of the bushing, and having thescrew-threaded projection b and cap cl, all arranged to operateSubstantially as shown and described.

2. The screw-threaded hollow plug B, havin'g the nut c, packing e', andopeningsbat one end, and the iiange b, packing m, and screwthreadedprojection b3 attbe other end, combined with theinternally-screw-threaded bushing A,l1aving the chambered head A?, andthe screw-cap d, substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
